    21D83M-843 FURNACE FAN CONTROL FOR LENNOX 83M00 50A66-122 50A66-123 WHITE RODGER

    Posted by Jerry L. Jones on 11th Aug 2020

    The new circuit board is working very well. I am not an electrician, but I have always done my own electrical work. Eight years ago I replaced the AC / Furnace control board myself. At the time, the replacement White Rodgers control board was identical to the bad Lennox board. Therefore the wiring was easy to swap out. This new White Rodgers board is different from the White Rodgers board that I installed eight years ago. The instructions and wiring diagram for this new board did not give complete wiring instructions for every wire, and three or four wires did not make sense to me. I had to call an A/C electrician to complete the job. He had no problem finishing the wiring. He also said the new board was the same as he always carries in his service van. He said the new board can replace several other boards by other A/C manufacturers.

    Controller for Lennox Furnace

    Posted by Chris on 4th Apr 2019

    Just installed, but works perfectly so far. Saved me around $200-$300. McCombs Supply Co Inc is a great place for the right products at a greatly reduced price.

    Exact replacement part

    Posted by Joseph on 13th Nov 2017

    Heating repair tech wanted $600.00 to replace the corroded circuit board which was causing the furnace the cycle the purge motor constantly. Suggested the money would be better spent for a new furnace. Part ordered from McCombs and arrived two days later. Works perfectly. THANKS!

    Exact Part and Quick Service!

    Posted by Eric Keim on 8th Mar 2017

    After determining our Lennox circuit board had failed, I started shopping on-line for a replacement part. McCombs had the part for unit, and it was at my front door within 4 days. According to an HVAC friend, McCombs' price was about half of what I would have paid locally. Got it all put together and the furnace is running great again. It seems a furnace or A/C will always fail when you need them the most. Thank you for the quick service, McCombs!
